My car has a XM button but when the car was made it did not have the option put into the car. Well ive been missing my xm radio so much, i hate messing with cds and regular FM radio is such a drag so i want my xm back
But since i have the button cant i just buy
and plug it in the factory input in the back of the radio and it work??
thanks guys if not obviously im just going to buy a new onyx or something from siriusxm
